The first wind guide member 140 may be formed with at least one annular outlet, and the annular outlet may be disposed to extend around an imaginary axis extending in the front-rear direction and configured to blow airflow forward, so as to promote ambient air around the natural wind inlet 1121 to flow forward and mix with heat exchange air blown out from the annular outlet, form warm, cool and uncooled comfort wind, and increase the air volume of the indoor unit 100.
Fig. 5 is a schematic cross-sectional view of an annular air guide 141 according to an embodiment of the present invention; fig. 6 is a schematic cross-sectional view of an annular air guide 141 according to another embodiment of the present invention; fig. 7 is a schematic cross-sectional view of an annular air guide 141 according to still another embodiment of the present invention. Referring to fig. 5 to 7, the annular air guiding member 141 may include a front side air guiding portion 1411 and a rear side air guiding portion 1412 having independent airflow channels, and the front side air guiding portion 1411 and the rear side air guiding portion 1412 are respectively provided with a front side annular air outlet and a rear side annular air outlet, so that the airflow from the front side annular air outlet guides the airflow from the rear side annular air outlet to flow forward, thereby increasing the overall air supply distance and air supply amount. The front and rear annular outlets may be formed inside the front and rear wind guide portions 1411 and 1412, respectively, i.e., on a side facing the imaginary axis.
The simulation experiment shows that under the same other conditions, compared with the air guide component with only one annular air outlet, the air guide component with the two annular air outlets in tandem not only obviously improves the air supply distance, but also improves the air supply quantity by at least 20%, wherein the total air outlet area of the air guide component with the two annular air outlets is equal to the air outlet area of the air guide component with only one annular air outlet.
The projection of the front side annular air outlet or the rear side annular air outlet on an imaginary plane vertical to the imaginary axis can be in a perfect circle, a rectangle circle, an ellipse and the like. The projection shapes of the front side annular air outlet and the rear side annular air outlet on the imaginary plane can be the same or different.
The inside peripheral wall, the outside peripheral wall, and the forward sidewall and the backward sidewall connecting the inside peripheral wall and the outside peripheral wall of the front wind guide 1411 and the rear wind guide 1412 may be provided with a smooth transition connection to avoid generation of vortex at the corners. The inner circumferential wall of the rear side air guide portion 1412 may be configured to extend gradually from the rear to the front to reduce wind resistance, so as to facilitate the ambient air to flow forward through the natural air inlet 1121 to be mixed with the heat exchange air.
The ratio of the outlet area to the inlet area of the front side air guiding portion 1411 may be smaller than the ratio of the outlet area to the inlet area of the rear side air guiding portion 1412, so that the flow rate of the air flow blown out from the front side annular outlet is greater than the flow rate of the air flow blown out from the rear side annular outlet, thereby improving the guiding effect of the air flow blown out from the front side annular outlet on the air flow blown out from the rear side annular outlet, and increasing the air blowing distance of the annular air guiding member 141.
The air inlet area of the front side air guiding part 1411 may be smaller than the air inlet area of the rear side air guiding part 1412, so that the air output of the front side air guiding part 1411 is smaller than the air output of the rear side air guiding part 1412, and the annular air guiding member 141 has a larger air output while having a longer air output distance. The area of the rear annular air outlet can be increased as much as possible to reduce wind resistance and enable airflow to flow more smoothly.
The front annular air outlet and the rear annular air outlet may be respectively and uniformly provided with a plurality of deflectors 1414 extending in the axial direction and the radial direction of the imaginary axis to reduce the amount of the airflow blown out by the front annular air outlet and the rear annular air outlet in the radial direction, so that the airflow blown out by the front annular air outlet and the rear annular air outlet is more uniform.
The rear wall of the airflow channel of the front side air guiding portion 1411 can be used as the front wall of the airflow channel of the rear side air guiding portion 1412, so that not only can the production cost be reduced, but also the airflow flowing change rules in the front side air guiding portion 1411 and the rear side air guiding portion 1412 can be consistent, the play amount of the airflow blown out by the front side annular air outlet and the rear side annular air outlet in the radial direction due to mutual interference is reduced, and the overall air outlet effect of the annular air guiding member 141 is enhanced. Among them, the backward side wall of the front side wind guide 1411 may be provided to be arched backward to guide the heat exchange gas in the back side wind guide 1412 forward.
The first wind guiding member 140 may further include a communication piece 142 communicating the volute outlet and the inlet of the annular wind guiding member 141. The communicating member 142 may be divided into two parts by a partition plate extending in a transverse direction to guide the air flow blown out from the volute outlet port to the front side air guide 1411 and the rear side air guide 1412, respectively.
Referring to fig. 5, in some embodiments, the front annular air outlet may be formed by sandwiching the forward side wall and the inner side peripheral wall of the front air guide 1411. The rear annular air outlet may be formed by sandwiching the forward side wall and the inner side peripheral wall of the rear air guide 1412.
The front side wall of the front side air guiding portion 1411 may be configured such that a tangent plane at any point of the inner end edge thereof extends in the front-rear direction, so that the airflow blown out from the front side annular air outlet flows in the front-rear direction, thereby improving the guiding effect of the airflow blown out from the front side annular air outlet on the airflow blown out from the rear side annular air outlet.
The inner peripheral wall of the front air guide 1411 may be configured to guide the airflow blown out from the rear annular outlet forward.
The inner peripheral wall of the front air guide 1411 may be configured such that a tangential surface at any point of the front end extends in the front-rear direction, so that the airflow blown out from the rear annular outlet flows in the front-rear direction, thereby enhancing the guiding effect of the airflow blown out from the front annular outlet on the airflow blown out from the rear annular outlet.
The inner peripheral wall of the front air guide 1411 may be disposed outside the inner end edge of the front side wall thereof, so that the distance between the rear annular air outlet and the imaginary axis is as large as possible, thereby increasing the volume of ambient air mixed with the heat exchange gas.
The annular air guiding element 141 may further include a flow guiding extension 1413 extending from a front end edge of the front annular air outlet to the front, that is, the distance between the flow guiding extension 1413 and the imaginary axis increases gradually from the back to the front, so as to increase the air supply area of the annular air guiding element 141.
The flow guiding extension 1413 may be disposed to be in smooth transition connection with the airflow passage of the front side air guiding portion 1411 to improve the smoothness of the airflow.
The flow guiding extension 1413 may be configured to extend along a curve, and an included angle between the flow guiding extension and the imaginary axis is gradually increased to further increase the air supply area of the annular air guiding member 141.

The rear annular air outlet may be formed by sandwiching the forward side wall and the inner side peripheral wall of the rear air guide 1412.
The rear end of the inner peripheral wall of the front air guide 1411 may be disposed on the rear side of the front end edge of the rear side wall thereof to adjust the flow direction of the heat exchange gas in the front air guide 1411 and to prevent the gas from being blown out from the outlet port in a messy manner.
The inner peripheral wall of the front air guiding portion 1411 may be configured to extend gradually from the rear to the front, that is, the distance between the inner peripheral wall and the imaginary axis gradually increases from the rear to the front, so as to increase the air blowing area of the annular air guiding member 141.
The inner peripheral wall of the front air guiding portion 1411 may be arranged to extend along a curve, and the included angle between the inner peripheral wall and the imaginary axis is gradually increased to further increase the air blowing area of the annular air guiding member 141.
Referring to fig. 7, in still other embodiments, the front side annular air outlet and the rear side annular air outlet may be gradually wider from a portion close to the communicating member 142 to a portion away from the communicating member 142, so that the wind resistance of the portion of the wind guiding portion away from the communicating member 142 is smaller than that of the portion close to the communicating member 142, and thus the wind volume at each position of the annular air outlet is more uniform. The minimum width of the annular air outlet can be 1/3-1/2 of the maximum width, such as 1/3, 2/5 or 1/2.
In the embodiments shown in fig. 5 to 7, the rear side edge of the front annular air outlet and the rear side edge of the rear annular air outlet may be both disposed outside the front side edge of the front annular air outlet, that is, when viewed from the front to the rear, both the front annular air outlet and the rear annular air outlet may be shielded by the front sidewall of the front air guiding portion 1411, so as to enhance the dustproof effect of the annular air guiding member 141 and improve the aesthetic property of the indoor unit 100 of the air conditioner.
In other embodiments, the rear side edge of the front side annular air outlet and the rear side edge of the rear side annular air outlet may be respectively disposed inside the front side edge of the front side annular air outlet and the front side edge of the rear side annular air outlet, that is, the front side annular air outlet and the rear side annular air outlet can be directly observed from front to back, so that the air flows blown out from the front side annular air outlet and the rear side annular air outlet can flow forward more smoothly.
In the present invention, the air outlet of the second wind guiding member 150 may be directly connected to the second air outlet 1112, so that the heat exchange gas directly flows to the second air outlet 1112 through the second wind guiding member 150. The air outlet of the second air guiding member 150 may be provided with a lower air guiding plate set 162. The lower air deflection plates 162 are controllably rotated in the lateral direction to adjust the blowing direction in the height direction. And the lower air guide plate group 162 may be configured to close the air outlet of the second air guide member 150 when the air inlet of the second air guide member 150 is sealed by the sealing portion 1212 or the impeller 122 is in a non-operating state, so as to prevent dust from falling.
The second wind guiding member 150 may also adopt the same structure as the first wind guiding member 140, so that the heat exchange gas and the ambient air are mixed and then flow out through the second air outlet 1112.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
